• Performing a fuzzy search may retrieve terms with similar spellings: tu cach tu hang cau hoi. hieu ((ve cam) OR (ve cac)) ((duc phan) or (suc manh)) hanh lam cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cach tu hang cau hoi. hieu ((ve cam) OR (ve cac)) ((duc phan) OR (suc manh)) hanh lam cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cach tu hang cau hoi. hieu ((ve cam) OR (ve cac)) ((duc phan) or (suc manh)) hanh lam cua triet*".
